Adele's Secret to Slimming Down

As a performer with incredible vocal skills, Adele will always be larger than life. But we can’t help but notice the singer has been sporting a smaller size when it comes to her physique over the past few years — and she has the Sirtfood Diet to thank for her slim down.

The diet is based on research surrounding sirtuins (SIRTs), a group of proteins found in the body that have “been known to regulate a variety of functions, including metabolism inflammation and lifespan,” according to Healthline. The idea is to eat a balanced diet full of sirtuins, along with exercise, to help you shed pounds pretty quickly. Sirtfoods include kale, strawberries, onions, walnuts, coffee, red wine, and dark chocolate (85 percent cocoa).

Coffee, wine, and chocolate? We love the sound of that! Of course, you can’t go overboard on the sweeter side, or really any part of the diet, but you don’t have to sacrifice your morning coffee or occasional glass of merlot to see results.

Before you dive in, there are a few more details of the diet to go over. Aidan Goggins and Glen Matten, authors of The Sirtfood Diet ($12.98, Amazon), break it down into two phases:

Phase one lasts seven days with the first three restricting your calorie intake to 1,000 a day and lots of green juice. After three days, you can bump that up to 1,500 and have slightly less green juice along with sirtfood-rich meals.
Phase two does away with the calorie restrictions, but still has one green juice a day and foods filled with sirtfoods. The book includes plenty of recipe examples like smoked salmon pasta and buckwheat pancakes.

You can repeat the phases as often as you’d like to reach your weight loss goals, but this is more of a short-term diet, versus a long-term eating plan. But you are still encouraged to continue drinking the daily green juice and pack your meals with sirtfood on the regular.

Remember, you should talk with your doctor to see if the Sirtfood Diet is the right option for you. If she gives you the okay, you might just find yourself looking as radiant and refined as Adele!
